Description
本発明のカメラシステムは、交換レンズとカメラボディとを含むカメラシステムであって、前記カメラボディは、被写体を撮像し、定期的に生成される第1のタイミング信号に応じて露光の開始と終了とを行って連続的に画像データを生成する撮像手段と、前記撮像手段での露光の開始と終了とのタイミングを把握して第2のタイミング信号を生成し、前記交換レンズに送信するタイミング信号送信手段と、を備え、前記交換レンズは、光軸方向に進退することにより、被写体像のフォーカス状態を変化させるフォーカスレンズと、前記フォーカスレンズの位置を検出する位置検出手段と、前記カメラボディから送信された前記第2のタイミング信号を受信するタイミング信号受信手段と、該交換レンズの動作を制御するレンズ制御手段と、を備え、前記レンズ制御手段は、前記カメラボディから受信した前記第2のタイミング信号に応じて前記フォーカスレンズの位置を検出するように制御を行う。 The camera system of the present invention is a camera system including an interchangeable lens and a camera body, and the camera body images a subject and starts and ends exposure according to a first timing signal generated periodically. And a timing signal for generating a second timing signal by grasping the timing of the start and end of exposure in the imaging unit and transmitting it to the interchangeable lens. The interchangeable lens includes a focus lens that changes a focus state of a subject image by moving back and forth in the optical axis direction, a position detection unit that detects a position of the focus lens, and a camera body. a timing signal receiving means for receiving the transmitted second timing signal, and a lens control means for controlling the operation of the interchangeable lens, Wherein the lens controller controls so as to detect the position of the focus lens in response to said second timing signal received from the camera body.
